MOUNIING FOR ELECTRlC- -CAR MOTORS.

SPECIFICATION forming part of Letters Patent No. 444,922, dated January20, 1891.

Application filed August 1 5, 1 88 9.

To all whom it may concern.-

Be it known that I, EDWIN WILBUR RICE, Jr., a citizen of the UnitedStates, and a resident of Lynn, in the county of Essex and State ofMassachusetts, have invented a certain new and useful Motor-Suspensionfor Railwayork, of which the following is a specification.

My invention relates to the manner of mounting or supporting theelectric motors employed in connection with railway-cars as a means ofpropelling the same.

The object of my invention is to secure an unvarying or rigid relationof the parts of the driving mechanism, while'at the same time securingflexibility or adaptation to shocks or vibrations of the vehicle.

My invention consists in the novel construction and combinations ofmechanism hereinafter described in connection with the accompanyingdrawings, and then specified in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a railWay-car truck having a motor mounted and supported in accordance with myinvention. Fig. 2 is a plan of the motor and its supporting devices.

F indicates a frame of any suitable material, consisting of two sidepieces and a crosspiece, preferably integral with one another, andhaving the ends of the side pieces sleeved upon an axle A of the car,which is preferably the drivingaxle. The crosspiece of the frame at theopposite ends of the side pieces F forms a support for one end of thefieldmagnet B.

G C are the polc-pieces of the field magnet, which pole-pieces areprovided with exten sions c, of brass or other suitable material,resting on the cross-piece.

The opposite end of the iicld-magnct that is, the yoke end-is sustainedby the crosspicces by means of a bar D, which is the yokepiece to whichthe field-magnet cores are bolt-ed, and is laterally extended, as shown,to permit it to be attached to the side pieces of the frame.

E is the armature of the electric motor, and G is the armature-shaftjournaled in the frame F, as shown.

His a shaft of the intermediate gear between the armature-shaft and thecar-axle A.

Serial No. 320,906. (No model.)

The shaft H is likewise journaled to the frame, as shown. The caps ofthe journal-bearings are indicated at I I, &c.

The end of frame F opposite the end which is sleeved upon the car-axleis preferably elastically supported between cushionsor springs S S,carried by a part of the truck-frame K, or by other suitable support.

YVhile I have shown the electric motor as supported byextensions of abar forming the yoke of the field-magnet, I do not limit myself to thisspecial device, since the yoke end of the magnet might be supported fromthe frame F by other means without departing from my invention. I preferto employ the particular manner described 011 account of its simplicity.

It will be seen that the bar D aids in giving rigidity to the frame inwhich the axes of the armature and core are supported.

\Vhile I have described the frame F as elastically supported from thetruck-frame K, I do not limit myself to this particular method ofsuspension for said frame, since it might be supported from other partsof the vehicle without departing from my invention. I prefer, however,to suspend it from the truckframe. The extension 0 is part of thenon-magnetic yoke which unites the ends of the pole-pieces C. Theextension 0 may be either applied to the cross-piece I or may rest uponthe same, so as to be capable of sliding freely on it. I prefer,however, to fasten it to the cross-piece F, so as to secure increasedrigidity.

IVhat I claim as my invention is 1. The combination, with the supportingframe carrying the journal-bearings for the armatu reshaf t, of theyoke-piece for the fieldmagnet extended laterally for attachment to saidframe.

2. The combination, substantially as de scribechof a frame F, consistingof side pieces sleeved at one end on the car-axle and a unitingcross-piece at their opposite end, an electric motor having an armaturejournaled in said side pieces, and a field-magnet supported at its yokeend from ithe side pieces and at its pole end by extensions from saidpoles resting on the cross-piece.

3. The combination, substantially as described, of a frame consisting ofside pieces and a uniting eross-pieee with an electric pieces at one endand having an extension 10 motor having a field-magnet supported atitsresting upon and bolted to the cross-piece.
